Face analysis is essential for a large number of applications such as human-computer interaction or multimedia (e.g. content indexing and retrieval). Although many approaches are under investigation, performance under uncontrolled conditions is still not satisfactory. The variations that impact facial appearance (e.g. pose, expression, illumination, occlusion, motion blur) make it a difficult problem to solve. This book describes the progress towards this goal, from a core building block – landmark detection – to the higher level of micro and macro expression recognition. Specifically, the book addresses the modeling of temporal information to coincide with the dynamic nature of the face. It also includes a benchmark of recent solutions along with details about the acquisition of a dataset for such tasks.

Facial landmark detection is an essential task for a large number of applications such as facial analysis (e.g., identification, expression, 3D reconstruction), human-computer interaction or even multimedia (e.g., content indexing and retrieval). Although many approaches have been proposed, performance under uncontrolled conditions is still not satisfactory. The variations that may impact facial appearance (e.g., pose, expression, illumination, occlusion, motion blur) make it a difficult problem to solve. In this thesis, a contribution to both the analysis of the performance of current approaches and the modeling of temporal information for video-based facial landmark detection is made. An experimental study is conducted using a video dataset to measure the impact of pose and expression variations on landmark detection. This evaluation highlights the most difficult poses and expressions to handle. It also illustrates the importance of a suitable temporal modeling to benefit from the dynamic nature of the face. A focus is then placed on improving temporal modeling to ensure consideration of local motion in addition to global motion. Several architectures are designed based on the two main models from the literature: coordinate regression networks and heatmap regression networks. Experiments on two datasets confirm that local motion modeling improves results (e.g. in the presence of expressions). These experiments are extended with a study on the complementarity between spatial and temporal information as well as local and global motion to improve the design of the proposed architectures. By leveraging these complementarities more effectively, competitive performance with current state-of-the-art approaches is achieved, despite the simplicity of the proposed models.

"Face recognition (FR) is one of the most convenient biometric systems even though it is not currently the most reliable one. Especially when images for (FR) system are captured by surveillance cameras, such cameras often produce low quality images which make recognition more difficult and less reliable. This study uses a recently published database called 'SCface database' which emphasizes the challenges of face recognition in uncontrolled indoor conditions such as lighting conditions, face pose, facial expression and distance to camera. More specifically, the recognition is done using different cameras of different resolutions and imaging sensors. The aim of this study is to examine the effect of camera quality and distance from the camera with regards to face recognition rates by analyzing different face recognition schemes such as Eigenfaces, Discrete Cosine Transform (DCT), Wavelet Transform, Gray Level Concurrence Matrix (GLCM) and Spatial Differential Operators (SDO). Principal Component Analysis (PCA), Zonal coding and spectral regression were also investigated as various dimensionality reduction approaches"--Abstract.

CYBER SECURITY AND DIGITAL FORENSICS Cyber security is an incredibly important issue that is constantly changing, with new methods, processes, and technologies coming online all the time. Books like this are invaluable to professionals working in this area, to stay abreast of all of these changes. Current cyber threats are getting more complicated and advanced with the rapid evolution of adversarial techniques. Networked computing and portable electronic devices have broadened the role of digital forensics beyond traditional investigations into computer crime. The overall increase in the use of computers as a way of storing and retrieving high-security information requires appropriate security measures to protect the entire computing and communication scenario worldwide. Further, with the introduction of the internet and its underlying technology, facets of information security are becoming a primary concern to protect networks and cyber infrastructures from various threats. This groundbreaking new volume, written and edited by a wide range of professionals in this area, covers broad technical and socio-economic perspectives for the utilization of information and communication technologies and the development of practical solutions in cyber security and digital forensics. Not just for the professional working in the field, but also for the student or academic on the university level, this is a must-have for any library. Audience: Practitioners, consultants, engineers, academics, and other professionals working in the areas of cyber analysis, cyber security, homeland security, national defense, the protection of national critical infrastructures, cyber-crime, cyber vulnerabilities, cyber-attacks related to network systems, cyber threat reduction planning, and those who provide leadership in cyber security management both in public and private sectors

This richly illustrated book presents a straightforward non-instrumental method of clinical facial analysis in preparation for aesthetic surgery, orthognathic surgery, and orthodontic treatments. After discussion of various practical aspects of facial examination and photography, analysis of different regions of the face and dentofacial deformities is discussed in a series of detailed chapters. At the end of each of these chapters, multiple-choice checklists are included that will help the reader to perform step-by-step regional analysis. Important features of the book are its multidisciplinary approach and the emphasis placed on the relationship between different parts of the face. This second edition has been thoroughly updated and includes a new chapter on recording and documentation relating specifically to aesthetic facial surgery.

This thesis focuses on novel technologies for facial image analysis, which involves three topics: face recognition under uncontrolled conditions, automatic facial age estimation, and context-aware fusion of face and gait. They are either key issues bridging laboratorial research and real applications, or innovative problems that have barely been studied before.

This book includes the thoroughly refereed post-conference proceedings of the 14th RoboCup International Symposium, held in Singapore, in June, 2010 - representing the scientific tracks structured in four sessions entitled simulation and rescue robots; robot perception and localization; robot motion and humanoid robots; and human robot interaction and semantic scene analysis. The 20 revised full papers and 16 revised short papers presented were carefully reviewed and selected from 78 submissions. Documenting the research advances of the RoboCup community since the predecessor symposium, this book constitutes a valuable source of reference and inspiration for R&D professionals interested in RoboCup or in robotics and distributed AI more generally.
